Lock him up and throw away the key - obviously this guy will never learn!!

In regards to
"When the homeowner stops someone and calls the police, his intent is to stop a crime, not endanger the welfare of a child. Not annoy or harrass the individual. So I think that's a fualndamental issue here: can these crimes be proven?"
If the adults intent was NOT to annoy or harrass the individual he wouldn't have opened the door, he would have immediately called the police and stayed inside. He (the adult) was obviously looking for some sort of confrontation.

I think I used to date Mr. 8 feet....
